摘要
本次设计内容涉及了机械制造工艺及机床夹具设计、金属切
削机床、公差配合与测量等多方面的知识。
空心齿轮轴加工工艺规程及其铣右端键槽的夹具设计是包括
零件加工的工艺设计、工序设计以及专用夹具的设计三部分。在
工艺设计中要首先对零件进行分析,了解零件的工艺再设计出毛
坯的结构,并选择好零件的加工基准,设计出零件的工艺路线;
接着对零件各个工步的工序进行尺寸计算,关键是决定出各个工
序的工艺装备及切削用量;然后进行专用夹具的设计,选择设计
出夹具的各个组成部件,如定位元件、夹紧元件、引导元件、夹
具体与机床的连接部件以及其它部件;计算出夹具定位时产生的
定位误差,分析夹具结构的合理性与不足之处,并在以后设计中
注意改进。
关键词:工艺、工序、切削用量、夹紧、定位、误差。
ABSTRCT
This design content has involved the machine manufacture craft and
the engine bed jig design, the metal-cutting machine tool, mon
difference coordination and the survey and so on the various knowledge.
The reduction gear box ponents technological process and its
the processing ￠ 140 hole jig design is includes ponents
processing the technological design, the working procedure design as well
as the unit clamp design three parts. Must first carry on the analysis in the
technological design to ponents, understood ponents the
craft redesigns the semi finished materials the structure, and chooses the
ponents the processing datum, designs ponents the craft
route; After that is carrying on the putation to ponents each
labor step of working procedure, the key is decides each working procedure
the craft equipment and the cutting specifications; Then carries on the unit
clamp the design, the choice designs the jig position part, like
locates the part, clamps the part, guides the part, to clamp concrete and the
engine bed connection part as well as other parts; Position error which
calculates the jig locates when produces, analyzes the jig structure the
rationality and the deficiency, and will design in later pays attention to the
improvement.
Keywords: The craft, the working procedure, the cutting
specifications, clamp, the localization, the error
